A MotoTRBO control channel has been logged on 450.3125 MHz for the last few months. This freq has been licensed to and used by KABC 7 engineering for years, however, CNN is also licensed on this freq. Last night I noted a similar control channel on the 450.1375 KABC 7 assignment desk channel. This morning that CC had moved to 450.1500 MHz which is solely licensed to CNN offices on Sunset Blvd.
